Abstract: Procédé de préparation de podophyllotoxine cristalline anhydre (composé 1) à partir d'un produit contenant de la podophyllotoxine, qui consiste à dissoudre ledit produit dans un solvant non aromatique et non halogéné dont le point d'ébullition à la pression atmosphérique ne dépasse pas 130 °C et qui contient au plus environ 1 % en volume d'eau, à refroidir ladite solution pour précipiter les cristaux de podophyllotoxine, à isoler les cristaux et à les sécher à une température qui est augmentée au cours du processus de séchage, mais qui est toujours telle qu'elle soit inférieure à la température à laquelle les cristaux s'agglomèrent ou fondent, le séchage étant poursuivi jusqu'à ce que le point de fusion soit de l'ordre de 183-184 °C et jusqu'à ce que la quantité résiduelle de solvant soit au plus 500 ppm. Lorsque le matériau de départ contient du solvant complexé ou adsorbé, un traitement initial sous forme d'évaporation azéotropique est appliqué pour enlever le solvant. Le rendement de podophyllotoxine pure est fortement accru si l'on ajoute de l'eau au mélange de cristallisation.

Abstract: A microcomputer comprises a detection circuit receiving an interrupt signal for generating a first detection signal when the detection circuit detects a level transition of the received interrupt signal from a low level to a high level, and a second detection signal when the detection circuit detects a level transition of the received interrupt signal from the high level to the low level. A first register is set by the first detection signal, and a second register is set by the second detection signal. A timer is provided to receive an internal clock for counting the received internal clock and to generate a synchronizing signal. A synchronous circuit receiving the first detection signal and the second detection signal for generating a capture signal in synchronism with the synchronizing signal. A capture register is coupled to the timer and receiving the capture signal, for storing the count value of the timer in synchronism with the capture signal. The first and second registers are connected to a interrupt processing unit so that when the first or second register is set, the interrupt processing unit requests an interrupt processing to a central processing unit, so that the central processing unit executes an interrupt processing while reading the content of the capture register.

Title: Air separation
Inventor: RATHBONE THOMAS
IPC: F25J3/04
Filed: 1994-04-25
Abstract: Cooled and purified air is introduced into a higher pressure rectification column 2 and separated into oxygen-enriched liquid and nitrogen vapour. A stream of the oxygen-enriched liquid is flashed through a pressure reducing valve 20 to form a mixture of liquid further enriched in oxygen and vapour depleted of oxygen. The liquid is reboiled by reboiler 26. A stream of the further enriched liquid is reboiled in condenser 24 and is introduced into a lower pressure rectification column 4 for separation into oxygen and nitrogen products. Reflux for the columns 2 and 4 is formed by condensing in condenser 14 nitrogen vapour separated in the higher pressure rectification column 2. A reboiler 48 provides an upward flow of vapour through the column 4. The condenser 14 and reboiler 48 take the form of a single heat exchanger. As shown in Figure 1, the reboiler 26 is located in a phase separator 6; as shown in Figure 2, the reboiler is located in a rectification column 60 containing liquid-vapour contact devices above the level at which fluid issuing from the valve 20 is introduced. In either example, oxygen-depleted vapour is condensed in the condenser 24 by heat exchange with the further enriched liquid and at least some of the resulting condensate introduced into the lower pressure rectification column 4.

Abstract: A hot and cold water mixing apparatus (10) wherein a movable valve disc (160) is moved slidingly in a casing body (30), and a mixing ratio of high-temperature water to low-temperature water which are discharged from a hot water port (116) and a cold water port (106) respectively is varied. The movable valve disc (160) is urged by a temperature sensible spring (130), and in the opposite direction by a bias spring (150). When the temperature sensible spring (130) is exposed to mixed hot and cold water, the spring constant thereof varies to move the valve disc (160) in the high-temperature water reducing direction to a position in which the force of this spring and that of the bias spring (150) are balanced with each other, so that mixed hot and cold water the temperature of which has been regulated to a target level is discharged. Between the movable valve disc (160) and temperature sensible spring (130), a spacer (190) is interposed, which separates the temperature sensible spring (130) by a predetermined distance from a position in which the high-temperature water and low-temperature are mixed, whereby mixed hot water is brought into contact with the temperature sensible spring (130) after the high-temperature water and low-temperature water have been thoroughly mixed with each other. Thus, a stable sliding movement of the valve disc (160) is secured.
